- introduce variable _BB_CONFIG_DEP to the new test harness.

  This is used to see if given tests should be run (are available) or not.
  Print "UNTESTED: descr" if the applet or feature is not available.
- add _BB_CONFIG_DEP to existing new.tests
- move old grep test to new test infrastructure and add a few more test for
  grep.
